How to Calculate Factor Pairs of 100
Step-by-Step Process
To find all factor pairs of 100, we need to identify all integers that divide 100 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 100 (v100 ≈ 10.00)
- For each factor found, its corresponding pair is calculated by dividing 100 by that factor
Calculation Example
Let's work through finding the factor pairs of 100:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 100 ÷ 1 | 100.00 | Integer result | (1, 100) |
| 100 ÷ 2 | 50.00 | Integer result | (2, 50) |
| 100 ÷ 3 | 33.33 | Not a divisor | - |
| 100 ÷ 4 | 25.00 | Integer result | (4, 25) |
| 100 ÷ 5 | 20.00 | Integer result | (5, 20) |
| 100 ÷ 6 | 16.67 | Not a divisor | - |
| 100 ÷ 7 | 14.29 | Not a divisor | - |
| 100 ÷ 8 | 12.50 | Not a divisor | - |
| 100 ÷ 9 | 11.11 | Not a divisor | - |
| 100 ÷ 10 | 10.00 | Integer result | (10, 10) |

More About Abundant Numbers
Abundant Numbers
An abundant number is a positive integer for which the sum of its proper divisors is greater than the number itself. The number 100 is abundant because the sum of its proper divisors (117) exceeds 100.
The smallest abundant number is 12, whose proper divisors are 1, 2, 3, 4, and 6, which sum to 16.
